WALL cons'rnnc'rron.

To all w hom z't may concern:

' Be it known that I, FRANK MoM. SAwYEii, citizen of the United States, residing atfour'edges so shaped that when the slabs are 7 r set up, intercommumcating as well as interbetween the slabs.

secting mortar channels or ducts .are formed These channels will extend both horizontally and vertically and the construction contemplated is such that the channels will be completely concealed.

It is also proposed to construct a wall of two sides or tiers spaced apart and connected at intervals by web plates and suitable ties.

'In carrying out the invention slabs are molded of plastic material thus when the slabs are superimposed in a wall intersecting and intercommunicating horizontal and vertical ducts are formed by the registration of the grooves of one slab-with those of the adjacent slabs.

of the slabs being in contact the be concealed. Fluid plastic maa concrete mixture can be poured into the vertical ducts from the top of the wall and Will flow down the vertical duct and laterally into the horizontal ducts. This mixture when set will form a bond or look, whereby the slabs will be secured against lateral displacement. Further the joints will be finished and will not require any trowel or pointing up work. Reinforcing rods may be placed in the ducts.

In forming a double or two sided wall, cross connecting webs and tie rods are em- The webs are shaped to form hollow studs into which the fluid mixture may be poured. Metal clips for holding the parts in place are also, used.

The construction of the webs and the reinforcing means is very important. \Veb plates are disposed vertically and trans versely of the wall in break-joint relation. Each plate is dished or channeled so that The edges ducts will terial such as Specification of Letters Patent.

and each is sur-. rounded by a groove or channel in its four edges;

formed. A plastic mixture may be poured into this duct and a solid stud produced. The tie rods pass through the stud and the metal clips and assist in registering the slabs and holding the vertically reinforo mg rods against lateral displacement owing to the tension of the tie rods or Wires.

' The invention will be more readily understood from a perusal of the following specification and by reference to the accompanying drawings, wherein:

Figure 1 is an isometric view of a wall embodying the invention,

Fig. 2 is a detail plan view,

Fig. '3. is a transverse vertical sectional view on the line 33 of Fig. 2,

Fig. 4 is a view through and 1Fig. 5 is a perspective detail of the. metal c 1p.

In the drawings thenumeral 1 designates one of the sides of the wall,

a flat rectangular slab molded of plastic material as desired. Each slab has channels or grooves 2 in its upper and lower edges and whereby each slab is completely surrounded by a continuous channel or groove. the slabs are assembled in a wall the grooves of one slab will register with those of the adjacent or contacting slabs so that vertical and horizontal ducts will be formed. The

It is obvious that the ducts will be Each slab has a shouldered vertical recess 4 at each end for receiving a vertical tongue on the end .of' a transverse we plate 6. In all cases horizontal and vertical reinforcing rods 7 and 8, respectively are placed in the ducts. When the wall is built to the desired height or at intervals during fluid plastic material is poured the building,

into the vertical ducts. This material or mixture flows down the ducts and laterally into the horizontal ducts and forms an integral bond whereby the slabs are locked transverse vertical sectional to contact when the slabs are assimilar channels or grooves 3 in its ends,

The web plates are constructed with a recessed or wide channel portion 9 in one side,

said portions registering when the plates are set up in contacting relation. The plates are uperimposed in break-joint relation as shown in Fig. 3. The tongues fitting in the recesses 4 hold the plates against lat ei'al displacement when fluid plastic material is poured into the vertical ducts formed by the portions 9. Tie wires 10 are passed between the plates and tied to the rods 7 and 8 at the intersections of the latter, this not only tying the intersections of the rods together, but tending .to bring the slabs into close contact with the ends of the plates. At each intersection of the rods and. the wires, an angular'inetal clip 11 straddles the tie wires and has divergent legs 12 hearing against the shouldered portions of the slabs. The clips are disposed. in the vertical ducts so that their vertical ridges bear against the an exemplification and the invention may be carried out in various other ways.

WVhat I claim, 1s:

1. A wall construction formed" of two 3 sides of slabs in which reinforcing rods arev concealed and connected by Web plates in Wl110l1 tie Wires are embedded, sa1dt1e wires being tied to the reinforcing rods, in con1- bination with metal clips mounted on the wires and rods at the intersection of the same and within the sides ofthe wall, said clips holding the rods in position against the transverse strain of the tie wires.

2. In a wall construction, two uprigh spaced sides composed of vertical slabs, vertical and horizontal ducts formed in the,

abutting edges of the slabs of each side,horiz'ontal and vertical reinforcing rods disposed in said ducts, cement cores surrounding the rods between the slabs, each slab having a shouldered recess at lts end, trans+ verse upright fweb plates having reduced shouldered ends and recessed sides,the web plates being disposed with their recesses in registration and their reduced ends embedded -in the end recesses of the slabs, the

ing vertical duct for receivinga plastic ma- .6 registering recesses'of the plates constitut terial, cross wires extending from the intersections of the rods in one side through the recesses of the plates to the intersections of the. rods in the other side.
